Can I make a program which is randomly selecting an int value from an array?For example this is my array:

int []numArray = {12,45,36};

Can I make the class Random choose from that array? Or is there anything that can do that?

Hint :- You can use Math.random();

It's very easy. Generate a random number between 0 and the size of the array minus one. Use that random number as an index into the array.

Even easier if you find the correct method in java.util.Random.
